Pasha, or rather, can you remember where it came from? And is it possible to get this information somehow? For Karelia, I know for certain only one normally existing population of Psophus stridulus - on the Klimenetsky Island in Lake Onega (62° N), where nothing threatens it yet; the biotope is a dry meadow on a rock full of vipers.

It is necessary to contact Oleg Valersky - he leads an entomological circle in the city Palace of young People's Creativity in St. Petersburg. The year before last, he had material from Karelia - live males of Ps. stridulus and females of Podisma pedestris. He got them from someone and gave them to me for experiments - but the pzofuses didn't suit me because of the black eyes (anyone who read the article will understand

). By podisms, I specified the collection point - I only have information about the fact that this is the Lahdenpohsky district. Pzofusy were going, in my opinion, somewhere in the same place, but it would be better to clarify. I'll ask if I can." Or read his personal e-mail

.

You also seem to have a ratchet right in the city limits. Although, maybe, the wrong definition of psophus...

Yes, I also suspect that the probability that this is pzofus is higher. Although anything can happen. Especially in Duderhof, where this summer was the year of the real song cicada, Cicadetta montana. There are also broad-leaved tree species growing there (although it is not clear whether there are remnants of relict forests of the "Holocene optimum" or whether all these are descendants of the planting of Carpathian saplings in the XVIII century). Although the eggs of cicadas were easily imported with shoots, but the locust pods were somewhat more difficult...

Thank you for the address, I'll try to contact you.
Well, Podisma is not very interesting to me, it occurs quite abundantly in some places, my northernmost find is O. B. Zhuzhmui in the White Sea (a little south of Solovki), but Psophus is in the Red Book of the Republic of Kazakhstan, and the points of old finds are mostly not confirmed

By the way, the wing length of P. stridulus females varies greatly? Here recently in the photo was presented a copy with shortened (not much) wings, and I saw only such

As for the hermit: I will try to see the fees determined by the late luminaries on my next visit to ZIN (possibly next week). In my experience, there are some very unpleasant errors in our locust identification codes. But in terms of eye size, formally, the hermit is more similar to Sph. coerulipes. True, I'm in GIMP's measure, and Bey-Bienko, go, on the eye.

About akrida-so far, I'm afraid, no way. Most likely (purely my IMHO, not supported by any research), the same species appears under the names A. bicolor and A. ungarica (hungarica) in relation to the south-western part of Russia and Ukraine. The only one geographically close to it is A. oxycephala (this is probably from the Volga region and further east, I don't know about the Ciscaucasia). In general, you need to wait for the revision. Or do it
